Ecology
Study the interactions between organisms and their environment. Our ecology quizzes explore population dynamics, community interactions, food webs, and the flow of energy through ecosystems. Understand the web of life.
Climate Change
The greenhouse effect, evidence of warming, ocean change, effects on living things, and ways to limit warming.
Biomes
Land and aquatic biomes: their climate, typical plants and animals, adaptations and where they occur.
Biodiversity
Genetic, species and ecosystem diversity, hotspots, ecosystem services, sampling methods and major threats.
Ecological Succession
Seral stages, models of succession, worked examples, disturbance, and changes in soil and biomass over time.
Invasive Species
What makes species invasive, how they spread, their ecological and economic impacts, and how to control them.
Endangered Species
IUCN Red List categories, causes of species decline, extinction, and conservation tools with famous examples.
Food Webs & Trophic Levels
Producers, consumers, and decomposers.
Ecological Levels
Organism, population, community, ecosystem.
Community Interactions
Predation, competition, mutualism, and commensalism.
Biogeochemical Cycles
The Carbon, Nitrogen, and Water cycles.
Population Dynamics
Exponential vs. logistic growth, carrying capacity.
Dictionary
Key Ecology Terms
Plain definitions, with how to say each word and where it comes from.
- Biodiversity
Biodiversity is the variety of life in a place or on Earth as a whole, from genetic differences within species to the range of species and ecosystems.
- Biome
A biome is a large region of Earth defined by its climate and its typical plants and animals, such as tundra, desert or tropical rainforest.
- Carbon cycle
The carbon cycle is the movement of carbon among the air, oceans, living things, soils and rocks through processes like photosynthesis and respiration.
- Carrying capacity
Carrying capacity is the largest population of a species that an environment can sustain over time with the food, water and space available.
- Competition
In ecology, competition is an interaction in which organisms needing the same scarce resource, such as food, light or space, reduce each other's success.
- Decomposer
A decomposer is an organism, mainly a bacterium or fungus, that breaks down dead organisms and wastes and returns their nutrients to the environment.
Career
Where Ecology Leads
Careers that use it: what each job is, how people get in and what it pays.
- Conservation Officer
Protects and manages wildlife, habitats and green spaces, balancing the needs of nature with farming, visitors and local communities.
- Ecologist
Studies how plants, animals and their surroundings affect each other, and uses that knowledge to protect habitats and guide land use.
- Environmental Scientist
Investigates pollution and other hazards in air, water, soil and food, and advises on how to reduce harm to people and nature.
- Zoologist
Studies animals: how they behave, evolve, fall ill and interact with their habitats, both in the wild and in captivity.
- Marine Biologist
Studies life in the oceans and along coasts, from plankton to whales, and how it responds to fishing, pollution and warming seas.
- Plant Scientist
Studies how plants grow, fight off disease and respond to soil and climate, and uses that knowledge to improve crops.
